Pypilot Autopilot
The pypilot plugin provides an interface to the free software autopilot pypilot. Control, configure and calibrate the autopilot from OpenCPN.
The Pypilot_pi interface plugin will work with any operating system running opencpn (Linux, Windows, MacOS, Android are available). The Pypilot_pi interface plugin is separate and distinct from the plugin “autopilot_route_pi”.
The pypilot server that pypilot_pi connects to, so far typically runs on raspberry pi, but it can work on orange pi or potentially other systems as well.
Note: OpenCPN can communicate with pypilot server already via nmea to receive compass heading, and to autopilot, and this plugin is not strictly required. The plugin allows for configuration and tuning of the autopilot in ways not possible through basic nmea0183 messaging. The plugin also allows for graphical overlays of the autopilot settings directly onto the chart.

Pypilot Webapp if using tinypilot, creates a webserver which provides remote autopilot control through a browser. Trimaran test used rtlsdr IR remote for control. It can use any tv remote, also buttons, or gui program through openplotter.
This Autopilot uses modified and improved versions of SignalK and RTMUlib2. More details are available in the Wiki and README

Pypilot is free software like Opencpn and it is fully supported by opencpn, and is better supported than any autopilot. It has 2 specialized opencpn plugins designed for it. For the cost of a raspberry pi, some $4 sensors, and a motor controller you can build, or buy for $75 and just use a windshield wiper motor and a belt to the wheel, or if you have a tiller:
